The mission of the International Children’s Digital Library Foundation is to excite and inspire the world's children to become members of the global community – children who understand the value of tolerance and respect for diverse cultures, languages and ideas -- by making the best in children's literature available online.

Perseus is an evolving digital library, engineering interactions through time, space, and language. Our primary goal is to bring a wide range of source materials to as large an audience as possible. We anticipate that greater accessibility to the sources for the study of the humanities will strengthen the quality of questions, lead to new avenues of research, and connect more people through the connection of ideas.

Vidyanidhi (Meaning 'Treasure of Knowledge' in Sanskrit) is India's premier Digital library initiative to facilitate the creation, archiving and accessing of doctoral theses. Vidyanidhi is an information infrastructure, a digital library, a portal of resources, tools and facilities for doctoral research in India. Vidyanidhi is envisioned to evolve as a national repository and a consortium for e-theses through participation and partnership with universities, academic institutions and other stake holders. Vidyanidhi enhances access to Indian theses and enlarges the reach and audience for Indian doctoral research works.

The UCT Computer Science Research Document Archive archives and makes accessible documents that are products and by-products of research in the department.

DIGITAL COLLECTION
A collection of library or archival materials converted to machine-readable format for preservation or to provide electronic access (example: Thomas Jefferson Digital Archive, a project of the Electronic Text Center, University of Virginia Library). Also, library materials produced in electronic formats, including e-zines, e-journals, e-books, reference works published online and on CD-ROM, bibliographic databases, and other Web-based resources. In the United States, the Digital Library Federation is developing standards and best practices for digital collections and network access. In the meantime, the National Information Standards Organization (NISO) has published A Framework of Guidance for Building Good Digital Collections (Second edition, 2004).

DIGITAL LIBRARY
A library in which a significant proportion of the resources are available in machine-readable format (as opposed to print or microform), accessible by means of computers. The digital content may be locally held or accessed remotely via computer networks. For a distributed example, see the Mountain West Digital Library established by the Utah Academic Library Consortium. In libraries, the process of digitization began with the catalog, moved to periodical indexes and abstracting services, then to periodicals and large reference works, and finally to book publishing. Abbreviated d-lib. Compare with virtual library. See also: Digital Library Federation and National Science Digital Library.

Digital library
Collection of texts, images, etc., encoded so as to be stored, retrieved, and read by computer.

Digital libraries are organizations that provide the resources, including the specialized staff, to select, structure, offer intellectual access to, interpret, distribute, preserve the integrity of, and ensure the persistence over time of collections of digital works so that they are readily and economically available for use by a defined community or set of communities

A digital library is defined by Clifford Lynch (Chapter One of the CNI White Paper on Networked Information Discovery and Retrieval) as an "electronic information access system that offers the user a coherent view of an organized, selected, and managed body of information". Paul Duguid (Report of the Santa Fe Planning Workshop on Distributed Knowledge Work Environments) describes a digital library as "an environment to bring together collections, services, and people in support of the full life cycle of creation, dissemination, use, and preservation of data, information and knowledge".

This document is designed to help those who are contemplating setting up a digital library.
Whether this is a first time computerization effort or an extension of an existing libraryÕs services,
there are questions to be answered, decisions to be made, and work to be done. This document
covers all those stages and more.

Four core entities:
    * Collections (organized groups of objects)
    * Objects (digital materials)
    * Metadata (information related to objects)
    * Projects (initiatives to create or manage collections)

A good digital collection is created according to an explicit collection development policy that has been agreed upon and documented before digitization begins.

This workbook book offers practical advice as well as work sheets you can use to get started with your
own repository programme.

This report works from the assumption that to be sustainable, a digitization program should have certain intrinsic features. It should
• be integrated into the fabric of library services;
• be focused primarily on achieving mission-related objectives;
• be funded from predictable streams of allocation, be they external or internal; and
• include a plan for the long-term maintenance of its assets.

[...] set of selection criteria for digital imaging projects, which are divided into three categories:
- Collection development
- Handling and use
- Added value

Selecting Materials to Be Digitized Digitization projects based on federally held collections and information holdings and supported by dedicated funding should:
- support lifelong education and learning
- reinforce a shared national consciousness and informed citizenship
- be linked to economic growth and job creation

Decisions to select materials for digitization should also be based on a business-like approach that:
- identifies target user populations
- understands the needs and expectations of the users
- identifies measurable deliverables that will demonstrate benefits
- includes a promotion/marketing plan
- provides itemized costing
- takes into account the work necessary for obtaining copyright clearance for the material to be digitized

Selection for digitization is a complicated process having much in common with selection for purchase, microfilming, and withdrawal and with other strategic decision-making that is integral to the work of librarians and curators.

Las bibliotecas y los archivos ponen en marcha programas de digitalización de imágenes para satisfacer necesidades reales o que han sido percibidas. Es más probable que la utilidad de las imágenes digitales quede garantizada cuando se definen claramente las necesidades de los usuarios, se conocen los atributos de los documentos, y la infraestructura técnica de apoyo de la conversión, gestión, y entrega del contenido es la apropiada para las necesidades del proyecto.

Creation of digital versions of print, photographic, archival, and other materials may be undertaken for a variety of purposes, ranging from in-depth research to popular entertainment, and from large-scale projects to conversion of a few items for an individual’s use. It is expensive to select, create, and maintain digital resources; the cost of image capture accounts for only one-third of the total expense. It is therefore important to assure during the selection process that issues of technical feasibility, intellectual property rights, and institutional support are considered along with the value of the materials and the interest of their content.

As libraries move into the digital age, they increasingly face copyright and other intellectual property questions. Creating digital surrogates and using digital technologies to make copyrighted works available to the public raise many issues.

Digital preservation research has made important gains in recent years, and the capability for libraries and archives to manage digital collections continues to grow. This is obviously good news in that an expanded body of digital records, publications, and other objects will be preserved and made available. What is less obvious is that there is no magic bullet in the offing for dealing with all permanent digital materials: only a fraction will meet necessary conditions for optimal preservation and use. Materials that deviate from these conditions can still be included in digital collections, but finding and using them will be more difficult, perhaps substantially so. This article outlines conditions that govern the persistence of digital materials and suggests a model for future levels of service for digital repositories.
